Def Leppard recently confirmed June 7th as the North American release date for Mirrorball (Bludgeon Riffola/Mailboat Records), which will be available exclusively at Walmart and Sam's Club locations in the United States and Canada. The album will include a 50 minute DVD that contains live performances and intimate backstage footage of the band captured on the road. A special limited vinyl edition will also be made available. Mirrorball will also be available online, marking the first time the band's music will officially be made available for digital purchase. Def Leppard will also be releasing their new community based website in May, which is being developed to be the ultimate Def Leppard fan experience and go-to destination for all things on the band.

Said singer Joe Elliott: "To be able to say at last, we have a live album out and it be a three disc package which includes a DVD makes me very happy... it's the soundtrack of OUR lives...!"

Def Leppard's Mirrorball will be released through Bludgeon Riffola/Mailboat Records in Germany/Switzerland/Austria on June 3rd and the UK/Europe on June 6th.

Mirrorball was recorded across the world over the course of many of the band's sold-out dates and features all of the classic songs that have made Def Leppard one of the most respected and beloved power rock bands in the world. Mirrorball is Def Leppard's first ever live album and features rock classics such as 'Animal', 'Pour Some Sugar On Me', 'Photograph', 'Nine Lives' and 'Rock Of Ages. The album also brings together three brand new studio tracks - 'Undefeated', 'Kings Of The Word' and 'It's All About Believin'.
